The changes from last week's World's Best 10K are still settling out. Last week, an error was found in our calculations from that race due to two mis-identified runners. The resulting corrections raised the race's competitive score even higher, which is why runners who jumped up last week (like Sammy Kitwara and William Chebor) moved up more this week, and others who underperformed there, like Ugandan Moses Kipsiro, fell a bit further.
